eRAiN-BINDER.

SPECIFICATION forming part of Letters/'Patent No. 283,456, dated August21, 1833.

Application filed February 3, 1883. (No model.) Y

To all whom t may concern,.-

Be it known that I, HENRY D. W. BAILEY, a citizen of the United States,residing at Canton, in the county of Stark and State of Ohio, haveinvented a new and useful Grain-Binder, of which the following is aspecication.

The objects ofmy improvements are, iirst,

to insure the laying of the cord by the binderarin upon and close to thecenter of the knotA ter-jaws; second, to provide a single device foroperating the movable ja\ Y; third, to facilitate the movements of theknetter mechanism. I attain these objectsby the mechanism illustrated inthe accompanying drawings, in Which.- y

Figure l is a perspective View of the knetter. Fig. 2 is asimilar viewwhen the loop of the knot is formed; of the saine when the movable jawis open. Fig. 4L is a perspective view or' the sha-ft and jaws detached.Fig. 5 `is a perspective view of the` jaw-operating camsleeve detached.Fig. 6 is a perspective vienv of the case or box with its dependingbushing, and Fig. 7 is the/ knot.

Similar letters referto similar parts throughf out the several views.

The knot-ter mechanism consists of a ixed jaw, k, having apoint, k,which is curved or bent, (although not` enough to interfere with jaws)acting somewhat as a hook to keep the cords from sliding over the pointswhen the knetter commences its revolution. This fixed jaw depends from ashaft, it, which has one side cut away (see k7, Fig. 4,) to permit thebinder-arm to pass close to its center. Attachedto the upper `end oithis sha-ft is a pinion, 1.1m, Vwhich 'meshes with the machinery ofother parts of the grain-binder. The fixed jaw referred to has a slotthrough which extends a movable jaw, la, which is pivoted to the same,as shown in Fig. 4. This-movable jaw is both opened and closed by asleeve, k, (see Fig. 5,) having a projecting cam-part, k1, on its loweredge. This sleeve has one side out away (see 7.11, Fig. 5,) to permitthe binder-arni to pass close to the center of the knot` ter-shaft.Bearing upon the upper surface of the sleeve is a platespring, 1, oneend of Fig. 3 is a. perspective View' which is pivoted to the box orcase k3, (see Figs. 1, '2, and 3,) or some other convenient point, andthe opposite end surrounds a bushing which depends from the said boxcrease, which incloses and supports the knotter-shaft previouslyreferred to. This bushing has one side cnt away (se-e Fic. 6, la) topermit theV binder-arm to pass close to the center of the knotterlshaft.The end of this spring, which encircles the bushing, is pivoted looselyto the upper surface of the cani-sleeve to prevent a rotary, and yet topermit a slight vertical, ino- -tion of the cam-sleeve. The function ofthis spring is to hold said cani-sleeve against the knetter-jaws and torelieve its rigidity.

The object of the vertical motion of the calin sleeve is to adjust thepressure ol' the movable jaw upon cords of'diiierent thicknesses ordifferent accidental thicknesses in the saine cord, thus holding thesaine with equal tenacity 5 also, enabling 4the k netter to revolvesmoothly, as Well as to operate with equal facility under varyingconditions. to theA binder-frame by means of the case or box l?.

The binder-arm has a side curve, the direc- .tion of which is from theknetter, as shown in The knetter is attached Fig. 1, and is againgradually curved toward the knetter, so as to bring the point inlinewith the main part of the bindenarm.` These curves are sufficient to andare used for clear ing the knetter-shaft during its revolution.

Then the binder-arm comes iorWard, carrying the cord that extends aroundthe sheaf, its point passes close to the center of the knottcrshaft bymeans of the Way formed by the cutaway sides heretofore described,whereby it is enabled to lay the cord upon and close to the center ofthe knotterjaws (see Fig. l) by the side o f the cord previously laidthere by the binder-arm during its retreat, thereby insuring the passageof the points of the knetterjaivs over the cords l l (which extend fromthe knetter to the sheaf) as the knetter revolves to form the loop ofthe knot, this being a re- 9 The side curve of the binderwarm, being atthis IOO point of time opposite theknotter, leaves the knotter-shaftclear, in order that it may revolve withoutv coming in contact with thesame. The knotter-shaft now commences to revolve, carrying with it theknotter-j aws, and their points pass over the cords l 1, while the cordso o (which extend from the lnotter to the cord-holder) pass under theheel of the xed jaw. As the knotter-shaft revolves yet further theprojecting cam' part k13 of the sleeve engages with the heel le of themovable jaw, depressing'it, and thereby elevating the point k. (See Fig.3.) As the knetter-shaft revolves yet further the point of the movablejaw passes over and the point of the fixed jaw passes under the cords oo. (See Fig. 3.) As the knetter-shaft revolves yet further to com pleteits revolution and to fully receive the cords o. o the heel of themovable jaw passes out" from under the projecting part of the sleeve,and immediately the projecting part engages with the forward part of themovable jaw, forcing it downward upon the cords and holding the sameagainst the upper surface of the iXed jaw, (see Fig. 2,) therebyinsuring a iirm knot as the cords are severed and the loop drawn overthe severed ends and stripped from offfthe knetter by other machinery ofthe grain-binder. As the binder-arm retreats to gather a new sheail itlays the cord upon and close Ato the center of the knetterjaws, and uponits return lays the cord upon the said jaws in the manner heretoforedescribed.

I ain aware that prior to my invention knotter-jaws have been operatedin various ways, and that the cord has been guided or drawn upon theknetter-jaws by different methods; but

What I claim as my invention, and desire to 4o secure by Letters Patent,is

I. The sleeve la, having a projecting cani part, 7cm, adapted to elevateand depress the l movable jaw k3, substantially in the manner and forthe purpose set forth.

substantially as shown and i'or the purpose specified.

45 2. The spring 7c, encirclingthe bushing and bearing upon thejaw-operating cam-sleeve,

3. The-knotter-shaft eut away on one side to 5o permit the binder-arm topass close to the center of the shaft, so as to insure the laying of thecord upon the knotter -jaws by the binder-arm. l

4. The cutaway knotter-shaft, combined with` 5 5 the inclosing-jaw,operating cam-sleeve, said sleeve being cut away on one side to permitthe binder-arm to lay the cord close to the center of the jaws.

5. The combination of the cutaway lznotter- 6o shaft, its inclosingcut-away jaw, operating cam-sleeve, and the bushing, also eut away onone side, as described, all as and for the purpose set forth.

6. The combination of the knotter and the 65 side-curved binder-arm, theknotter-shaft being cut away on one side, and its inelosingbushing andjaw-operating cam-sleeve each eut away on one side, whereby the layingof the cord on the knot-ter by the binder-arm is 7o Witnesses:
